Application filed April 7, 1825, bSerial' No. 21,405, and in France April 10, 1924.

rlhis invention relates to a w'ashin machine comprising a boiling tub which is journalled horizontally. a cylindrlcal basket provided with blades and pierced wlth holes and intended to hold washing.

The object of the invention is to obtain the automatic rotation of the basket by means of the motive force produced by the water boiling inthe tub and'which creates in it an upward current through the dlfferences in density and the rising of the 'steam as it forms.

The invention consists essentially, for this purpose, in creating upon the half of the `vbase of the ltulo which is faced by the idle surfaces ofthe blades, between this base and partof the said channel the basket, two chambers, one of which is formed on the base. itself of the tub, in the entire length of the tub, by a plate incurved coaxially to the basket, the said chamber being partly open at its lower end (towards the vertical axial plane) and connected at its upper end (towards the horizontal .axial plane) to a second chamber of smaller ca.-

pacity formed upon-it by 'a plate incurvedlike the iirst one co-axially to the basket, and having an aperture at its .lower part and a connecting passage at its u per part, each greater than the ower opening `of the first chamber.

The invention is illustrated by way of example in the accompanying drawing in whichz- Figure 1 is a ysection across the axis of rotation of the basket'taken along the line I-I in Figure 2.

'Figure 2 is a longitudinal section taken along the line II-II in Figure 1.

Figure 3 is .a v the front wall o which hasbeen removed.

In Figures 1, 2, and 3, they channel 17 'is fully open at its upper part to a channel 19 with a lower opening 20, while the lower 17 is partly closed y a plate 21 which only leaves two oriiices 22 the cross sectionrof which is less than that of the channel. 19 and of its opening 20 which is itself less than the cross section of the channel 17. The .tubhrbeing filled withv vpart with the said main outlet aperture at itsv lower, part, said paserspective vienT of the tub -said .water up toca certain level, and also a part of the'- channels 17 and 19, this water is made to boil by theapplication of external 4 1n part, through the channel 19 and its oriiice at an increased pressure or velocity,

giving rise to a current which is added to the ascending current already produced in the-interior of thetub by the differences of density and the rising of the steam as it is formed, this current exerting a pressure on the blades which helps to rotate the basket.

' Vhat I claim is A washing machine comprising in combination a tub for containing boiling water,

Asaid tub having a hemispherical bottom, a

cylindrical basket, said basket having holes pierced in it and beingrotatively suspended in said tub, turbine blades carried on said basket, a main chamber'formed on one half of the bottom inner surface of said tub, curving coaxially with the basket and the lower end of such chamber being in open communication with the tub interior, a seccapacity curving' coaxially with the basket, being disposed4 ond chamber of smallercentrally in relation to the main chamber and havlng a communication at its u per sage and aperture being each greaterthan the lower openings of the main chamber,

connecting from which steam, issuing in the direction of least resistance through the smaller chainber having the'largest orifice impresses upon lthe mass of water inthe tub movements of flux acting u onf the working surfaces Aof the blades in or er to rotate the basket.

In testimony iwhereof l name to this specification.
